Color vision is occasionally checked because loss of color perception is a sign of certain disorders of the retina (the light-sensitive inner layer at he back of the eyes) or of the optic nerve (which transmits impulses from the retina to the brain). In order to check for abrasions or ulcers, the conjunction (the transparent membrane covering the white of the eye and inside of the eyelids) and the cornea (the transparent dome that forms the front of the eyeball)may be stained with flourescein ( an orange dye).
